Description
Technical field
The present invention relates to a kind of hemostatic material and preparation method thereof.
Background technology
The most inevitably there is various accident, in carrying out emergency treatment and operation process, all may
Because massive hemorrhage causes malpractice the most dead.Therefore, the topically effective quick-acting haemostatic powder of patient is most important, effectively controls
Make blood and reduce the bleeding time become reduce mortality important measures.Clinical conventional hemostatic material such as hemostatic gauze,
Stanch fibre, tourniquet bandage in use have limitation, as bleeding stopping period is longer, easily with wound adhesion and be difficult to change dressings,
To the infection of wound with suppurate helpless.Quick-acting haemostatic powder and functional hemostasis will be the directions of following haemostatic medicament development.
Conventional Absorbable hemostatic material has Fibrin Glue, gelfoam, oxidized cellulose, microfibrillar collagen, chitosan
And Sorbsan etc..Their mechanism of action and using method are not quite similar, and haemostatic effect also has difference.But, mesh
Before the hemostatic gauze that is widely used clinically be the SURGICEL produced by Johnson & Johnson of the U.S. (Johnson&Johnson) company
Series absorbable hemostatic product SURGICELTM、SURGICELTM Nu-Knit、SURGICELTMFibrillar,
At home also known as " speed i.e. yarn ", the composition of above product is oxidized regenerated cellulose, and main difference is embodied in outward manifestation
Form, SURGICEL series of products have occupied extremely important status the most in the international market now, and receive medical science
The consistent favorable comment of domain expert.Meanwhile, domestic You Ji company has also produced similar hemostatic gauze, but due to material
Performance can not show a candle to speed i.e. yarn, uses expensive import hemostatic material so main clinically.
Oxidized regenerated cellulose is the derivant of cellulose, has good anthemorrhagic performance, biodegradable properties and nontoxic, mesh
Before have been used for multiple industry, including in the medical field, general use nitrogen oxides as oxidant, by cellulose unit
Hydroxyl oxidize on middle C-6 position is that carboxyl prepares oxidized regenerated cellulose.When it uses as hemostatic material, carboxyl-content should
It is 16～24%, to ensure its haemostatic effect.Oxidized regenerated cellulose hemostatic mechanism is as follows: oxidized regenerated cellulose contacts
Can adsorb substantial amounts of erythrocyte after blood, then the acidic carboxypolymer in oxidized regenerated cellulose structure can cause haemolysis, i.e.
Erythrocyte dissolves, ruptures, and discharges hemoglobin.Simultaneously as containing ferric ion, oxidation in hemoglobin
Regenerated cellulose can be with Fe3+In conjunction with forming brown blob of viscose, close, block blood capillary end and stop blooding.As can be seen here,
The hemostasis of oxidized regenerated cellulose is a series of Biochemical Engineering, and the carboxyl quantity in material structure has
Limit, the anthemorrhagic speed therefore causing oxidized regenerated cellulose material is relatively slow, causes such material cannot be applicable to tremulous pulse etc.
The massive hemorrhage situation at position.
During oxidized regenerated cellulose is being continually striving to carry out as the study on the modification of hemostatic material always.Doub et al. discloses
Use the method that oxidized regenerated cellulose is neutralized by the aqueous solution of sodium bicarbonate or calcium acetate, and use thrombin impregnated carbon
The oxidized regenerated cellulose that acid hydrogen sodium neutralizes, then freezes to process and be dried in this case to the fabric after dipping, system
Obtained a kind of efficient oxidized cellulose class surgical operation hemostatic material.In United States Patent (USP), Saferstein et al. describes use
The alcohol-water solution of salt of weak acid, such as sodium acetate, is neutralized to pH value between 5～8, this method by oxidized regenerated cellulose
Not only make oxidized regenerated cellulose can store with ambient-temp-stable, and the acid-sensitive material of similar thrombin can be loaded, enter
And improve the anthemorrhagic performance of oxidized regenerated cellulose material.They also find simultaneously, and Doub et al. uses sodium bicarbonate to neutralize
Method can cause oxidized regenerated cellulose fabrics part gel, deformation, and cause the oxidation regeneration fiber of final neutralization to be knitted
The hot strength of thing is too low to be applied in the hemostasis of reality.And the calcium acetate that Doub et al. mentions in the patent
Although the oxidized regenerated cellulose neutralized ensure that original form of fabric, but due to after neutralizing material calcium content too high, make
The mammal skin of contact position and other somatic cells can be produced zest during with, and use position to form big sending out
White granulation lump, hinders the bio-absorbable of material.
In sum, although the correlational study of oxidized regenerated cellulose is all had a very big significance by above achievement in research, simultaneously
Also the anthemorrhagic performance making material has obtained a certain degree of lifting, but it is typically small to be an up degree, i.e. improves effect poor；
And, the ameliorative way in research also can be to the mechanical strength of regenerated oxycellulose as styptic material and Bioabsorbable in the past
Can adversely affect, for the anthemorrhagic performance promoted by a small margin, modified effect is lost more than gain.
Summary of the invention
The material anthemorrhagic performance lifting amplitude that the invention aims to solve existing oxidized regenerated cellulose modified is little, machinery
Performance and the problem of bio-absorbable performance inequality, and a kind of fullerene/oxidized regenerated cellulose compound hemostatic material and system thereof are provided
